. My 'invention is an improvement in amusement apparatus and relateslmore'especially to the .provisioni of a carer carriage the motion ofwhich as it travels o-ver the rails will 23j.. 4add to theenjoymentofthe passengers. In the present instance my invention is in- .tended toprovide specialmeans for impart'- ing sidewise rocking motion to thedifferent .sections ofVv a train ofl V.cars connected together in theVmanner-'illustrated in mypriorPatent No. 1,789,140, dated January13,1931; that isto say,. the sectional carmay;` be designed ,torepresent an animal, for example analliga? ton-andthe rocking of thesections from side 2215 to sidein opposite directionswillimitate the nvcrawling or walking motionsof the animal While the ApassengersWithinthev car will eX- perience sensations similar tothose'in a rockngboat lf g My invention 'therefore contemplates' the provision of a truck foreach section of the car so constructed and loperable in connectionv.with thefbody Yofthe car, as to impartthe desired rockingk motionstothe connectedcar Q5sections, the. operatingz means including Iayeldablesupport fortlie car body and inter- Y posed connections atopposite sid-es of-the centerA of thetruck for imparting the rocking lmotion7 said means consisting preferably of J .30 reciprocating Arodseach operated by lan eccentric keyed to a shaft driven by la motormountedon thetruck and employed also in voperating thecar over thetracks; all as hereinafter fully described. and specificallyjset `f,`5kforth in the appended-claims., Y 1

As shown in Fig. 5the eccentric V.is provided `peripherally ywith a ridge 39 seated in acorresponding groove'in the ring,

.and the side flanges of the Alatter overlap the opposite sides of saideccentric which is fixed to the shaft by key 40. The outer end of thereciprocating rod or arm is connected to the under side of the car' bodybyy a bearing-box 4l attached lto the under side ofthe car by bolts 42,said bearing-box being in twoparts lbetween which the roundedouter endof the reciprocating rody or arm is yitted for slight turning movementtherein. rlhe eccentric is held on` the end of the shaft by means of anut 43 threaded on said shaft against the outer end ofthe hub on saideccentric, the nut being locked in place by a Cotter-pin 44, and

inA one instance the Yeccentric bears against the shaft-bearing 45,while in the other it bears against a collar 46 on the shaft 35, andlongitudinal movement of they shaft vin its at'the inner side of saidbearings respectively secured thereto by set screws 47a. The shaft onwhich the eccentric is mounted is driven from Vthe motor-driven axle byan interi mediate shaft 48 to which it is connected for operation bybevel gearwheels 49, 50, the said intermediate shaft being geared to theaxle by intermeshing worm-wheels 51, 52, and for lubricating.y the gearsthey are located within a pan or casing 53 supported in the truck asshown and having bearings 54 and 55 rising from the bottom thereof andin which the shafts are journaled. The shaft bearings'45 are in the formof ball-bearingsyas shown in `Fig? with an oil cup 56 in the upperplate-of the bearing which is attached to the side walls of the casingby bolts 57. Y

vrlhe bearing between the eccentric and ring at the inner end .of thereciprocating rod or arm is lubricated by a grease cup 58 at thelunderside of the ring and an oil cup 5.9

threaded into the upper section of said ring.

In the operation of theamusement car over the trackit is driven by theelectric-motor geared to the driving axle ofthe truck, and when the caris in two sectionsl connected t0- gether as illustrated in Fig. 2 andeach may be provided with a motor, for as-the eccentrics are turned fromthe axles one is directly operated by the motor driven axle while theother is operated by the wheels running over the track. As the` carspeeds over the track the reciprocating motions of the connecting rodsor arms between the truck and body ofthe car at oppositesides of thecenter thereof impart the desired rocking of the Vcar body sections andthe extent to which said sections are rocked will depend upon the throwofthe-eccentrics. lt will be noted that the springsupporting eachsection or body at approximately the centerv thereof permits va rockingmovement of each car body on the reciprocating rod. ,Y A

By providing an amusement car with rocking body sections mounted ontrucks and having rocking motions imparted thereto by the mechanismhereinbefore described it will for rock-ing motion one with respect tothe other, rods connected to and depending from the car bodies atopposite sides of the center thereof,'a driven shaft on each truck, andmeans interposed between the driven -shafts and aforesaid rods forimparting krocking motions to said car bodies.
